This invention relates to a particular construction for making a tightjoint between the sash and frame of a window adjacent the sill, and contains matter derived from my earlier application Ser. No. 165,526, filed Feb;

able to make a very efficient joint between 39, the sill and the sash in a window of the type i in their inner walls to receive the lower sash comprising jambs having a vertical opening and enlarged chambers back of such opening.

In a window of thisconstruction it is highly desirablethat the lower sash be pressed outs ward so'that it will make a tight joint with the parting strip or baflie which provides the outer edge of the vertical opening in which the sash moves. In previous constructions with windows of this type there'hasbeen a compromise alon thesill where the sash was forced inwar to form a tight joint along the sill line but left a space for air leakage on the outside between the sash and bafiie.

' I have found that this can be overcome by providing a spring member which is adapted.

to push the sash outward against the baffle but will exert pressure for substantially the width of the sash between the fixed Slll portions and the sash. Such spring member may be attached to the" sill but I attach it to the sash.

My invention may be readily understood by reference to the accompanying drawings in which Fig. 1 is a sectional view through the sill and sash showing a portion of the j amb face and Fig. 2 is a section on line 22 of Fig.1 but with the sash raised so that it again upwardly, as indicated at 12, to form' a glass rabbet. Plate 10 is adapted to extend down to meet the sill 14 which has a horizon- V wmnowsILL Ann sAsncoNsrBuoTIona;--

Welded 'on'ithe outside of the plate 10 is astop 22-whichf1ocks in place a weathen seal 24 which isjbent "around, the lower part of theplate 10 and is adapted to make spring contact with the corner 17, formed by the meetingof portiens 16fand 18 o' f the[sill.

The position which the upper central 'pors tion Of the stop 1 24: will assumerelative to the plateflO when the lower sash is'raised', isindicated bybroken lines in Fig.1. I y

In the construction hereillu'strated, the sill 14 extends beyond theinner face of the jamb walls at least asffar as'partition member 25, and plate 10 extends 'practicallyfto the partition m e1'nber, as indicated in broken lines n Fig. 2.* Member 24'is preferably made the same length as plate .10. The iiiner jamb wall isfformed in three parts; The

portion 26 lies above the horizontal portion 16 of the sillland liasjits lower corner" cut oifas'indicated at 28 to permit of movement of the-upper edge'of weather "sto p 24. The parting strip or baflle 30 is positioned away from portion 26 far enough tdform a slot 32, and the: balance of the inner jamb wall is formed by plate 34 I (whichiis here shown as integral with partition 25), leaving a slot 361 e ween it'.a11d :the p'arting strip 30.

As shownin Fig. '2, thereare enlarged chain here back of slots "32and 36. The'memb'er 38 is welded on the plate 10 to form a glass channel 40. This channel slightly wider than the thi'cknessof glass to be used 'but is partly filled 'by the hook-shaped member 42 which contacts with the horizontal portion 16 of thesill, and is held inplaceby screws not hereshownf By this arrangement an eflicient joint be-V tweenthe sill and sash is formed which ex tends into the jamb to thepoint where the sash. makes rubbing contact with a partition member in the/jambso that there is' substantially no chance forleakage atthe corners ofthe sash.
